WARREN A. PATTERSON, OF DALLAS, TEXAS, ASSIGNOR T0 COTTON HARVESTERCOMPANY, OF ST. LOUIS, MISSOURI.

COTTON-CLEANER.

To all 0117mm it may concern Be it known that I, \VARREN A. PATTER- soN,citizen of the United States, residing at Dallas, in the county ofDallas and State of Texas, have invented certain new and usefulImprovements in Cotton-Cleaners, of which the following is aspecification.

My invention relates to new and useful improvements in cotton cleaners.Its object is to provide a machine for cleaning seed cotton before thesame is ginned, and for ren'loving all of the dirt, hulls, twigs andother foreign matter, such as are usually accunmlated with seed cottonduring the process of picking the same, more particularly whenmechanical means are em ployed to gather the cotton.

The object of the invention is more specifically to provide a cottoncleaning ma chine comprising a rotatably mounted cylinder having slattedwalls, and a means to gradually shift cotton, constantly supplied at oneextremity of the cylinder to the other end thereof, the foreign matterbeing permitted to escape through the slats of the cylinder during thisprocess.

The object of the invention is finally to provide a device of thecharacter described that will be strong, durable, simple and efficientand comparatively easy to construct, and also one that will not belikely to get out of working order.

ith these and various other objects in view, my invention has relationto certain novel features of the construction and operation, an exampleof which described in the following specification and illustrated in theaccom mnying drawings, wherein:

Figure 1 is an end elevation of the cotton cl aning machine, the samebeing viewed from the discharge extremity of the cylinder. Fig. 2 is aside elevation of the salne. Fig. 3 is an axial vertical sectional viewof the cylinder, the section being taken upon the line X*X of Fig. 1.looking in the direction of the arrows. Fig. 4 is an axial, horizontalsectional view of the cylinder. the section being taken upon the lineY--Y of the Fig. 1, looking in the direction of the arrows. Fig. 5 is atransverse, sectional detail view of a portion of the cylinder wallshowing the slatted construction thereof. Fig. (i is a detail viewshowing a portion Specification of Letters Patent.

the cylinder from said slats to retain the cotton. Fig. 7 is alongitudinal, sectional, detail view of a special form of air out-let,adapted to project a blast of air into the cylinder along the entirelength of its Wall, the section being taken upon the line ZZ of Fig. 1.

Referring now more particularly to the drawings, wherein like referencecharacters designate similar parts in all the figures, the numeral 1denotes three large metal rings, which form part of the cylinder framework, one of said rings being disposed at each extremity of thecylinder, and the third one at a point midway between the two end rings.Each of said rings is provided with a flange member 2, of a diametersomewhat less than that of the outer periphery of the ring. The flangemembers of the two end rings face toward the discharge end of thecylinder, and that of the middle ring faces toward the in-let end of thecylinder. A rigid connection is formed between the three rings 1 by aplurality of parallel rods or pipes 3, passing centrally through therings at equidistant points, a sufficient number of the members 3 beingemployed to produce a strong cylindrical, frame work. The pipes 23 alsopass through a number of large wooden rings at, one of which is locatedclosely adjacent to each of the end rings 1, and one at each side of themiddle ring 1. To the outer surfaces of the wooden rings it there aresecured a plurality of spaced slats of composite construction. Each slatcomprises a member 5 substantially square in cross section and nailed orotherwise secured to the wooden rings at and a wedge shaped member 6surmounted upon the member 5 with its sharp edge outermost. The members5 and 6 will both preferably have the nature of strips of wood, althoughother materials might be employed for the purpose. The elongated slot orspaces between the slats will be of such a width thatleaves, twigs.hulls and similar foreign matter will be able to pass through. Aplurality of sharp spikes 7 slightly spaced from each other are embeddedin each of the members 5, their pointed extremities being permitted toproject a short distance into the cylinder from said members.

In order to support the cylinder in a horizontal position, the flange 2,carried by each of the rings 1, is allowed to rest upon a pair of largerollers 8, mounted in transverse alinemcnt in such a manner as tocontact with the opposite lower portions of said flange. The threerollers 8 which are thus disposed at each side of the cylinder aremounted fast upon a horizontal shat't mounted in three bearings 10, oneof which is located adjacent to each of said rollers. The bearings 10 ateach extremity of the cylinder are supported by the end portions of ahorizontal. cross piece 11 upheld by wooden uprights 12. The spacebetween the cross pieces 11 and the floor is boarded in atcach extremityforming the vertical wall designated by the numeral 13. The two bearings10 which support the middle portions of the shaft 9 are each surmountedupon a post 14, secured to the floor upon which the machine rests. Inorder to communicate rotation to the cylinder, a sprocket wheel may bemounted upon one of the shafts 9, as indicated at 15, said sprocketwheel forming part of any suitable mechanism for communicating rotationto the shaft. The rotation to which the shaft 9 is thus subjected willbe imparted to the cylinder due to the heavy friction set up between theflanges 2 and the rollers 8 and occasioned by the weight of thecylinder. As an additional precaution against a possible displacement ofthe cylinder either in a longitudinal or transverse direction, a pair ofrotatably mounted rollers 16 are made to contact with opposite upperportions of the flanges carried by the end rings 1. The two rollers 16at each side of the cylinder are mounted fast upon a horizontal shaft17, the extremities of which are mounted in hanger bearings 18,depending from the extremities of cross pieces 19 horizontally mountedupon the upper end of the uprights 20, two of which uprights areprovided at each extremity of the cylinder, their lower ends beingsecured to the cross pieces 11. The skeleton frame work formed by thecross pieces 11, 19 and 20 in combination is further reinforced by apair of parallel, horizontal beams 21 extending longitudinally above thecylinder and having their extremities secured to end portions of thecross pieces 19.

At the inlet of the extremity of the cylinder there is provided aninclined chute 22, having its lower end supported slightly above thebottom of the cylinder by a cross piece 23 rigidly extended between theadjacent uprights 20. The upper extremity of the chute is shown in thedrawings as supported by a post or vertical bar 24, but it should beunderstood that a cotton elevator (not shown) will support the upperextremity of said chute and will discharge its contents into the same.

A description will now be given of the mechanism provided to produce agradual displacement of the cotton from the inlet to the discharge endof the cylinder as the latter is rotated.

The two pairs of uprights 20 respectively provided at each end of thecylinder are connected by apair of oppositehorizontalbeams 25, passingthrough the cylinder. Thebeams carry upon their upper edges a pluralityof equidistant bearing members 26, six of said members being shown inthe drawings supported by each beam. Each pair of bearing members 26supports the extremities of a rock shaft 27 mounted transverse of thecylinder, all of said rock shafts being in the same horizontal plane.Each of said rock shafts supports a plurality of downhanging. parallelrods 28, their number being sutticicnt to produce a spacing such thatthe bolls of cotton will not pass between the said rods. From one end ofeach of the three rock-shafts and adjacent to the inlet extremity of thecylinder, a pin 29 extends upwardly a short distance parallel to therods 28. The upper extremities of. the three pins 29 each has pivotal.connection with a horizontal bar 30, extending longitudinally of thecylinder, and projecting a short dis tance from the cylinder at thedischarge end thereof. Similarly a horizontal bar 31 has pivotalconnection with one of the end rods 28, carried by each of therock-shafts 27 nearest adjacent to the discharge end of the cylinder,the points of pivotal connection in this case being below therock-shafts. The projecting free end of each horizontal bar 30 and 31 issupported by a hook member 32, two of which members are carried by oneof the u]n'ights 20 at the discharge end of the cylinder. The bars 30and 31 form elongated handles by which the rock-shafts may be subjectedto a slight angular displacement, two of said handles being providedthat it may be possible to adjust onehalf of the rock-shafts separatelyfrom the other half. It is obvious that this adjustment may beaccomplished in either case by subjecting the rods 30 and 31 through aslight longitudinal displacement. Between the two uprights Qtl at thedischarge end of the cylinder is mounted the lower edge end of aninclined chute 32, extending into the cylinder at a slight inclination,a pair of bracket members 3?) serving to support the lateral edges ofsaid chute from said uprights. The upper edge of the chute terminates ona line substantially beneath the rock-shaft nearest adjacent to the discharge end of the cylinder.

A description will now be given of a mechanisn'i employed to dischargea. blast of air radially into the cylinder along the entire lengththereof.

At one side of the cylinder a blower fan 31 is mounted upon a suitabletable 35, a driving pulley 36 being carried by the fan shaft and adaptedto receive rotation from any suitable source of motive power. The fanoutlet communicates with a pipe 37 which rises vertically adjacent tothe middle portion of the side of the cylinder. Four branch pipes 38COD'III'llUliCltG with the upper extremity of the pipe 37 and areadapted to discharge at four different points into an elongated box orcasing 39 wedge shaped in cross section having a discharge opening extending the entire length of its reduced edge. A plurality of equallyspaced vertical partitions 40 are diagonally mounted in the casing 39(see Fig. 7) for the purpose of deflecting the blast of air dischargedfrom the casing slightly toward the discharge end of the cylinder. Itwill later be made clear how the blast of air discharging from thecasing 39 is employed to blow the seed cot ton from the cylinder wall sothat it may fall upon the series of inclined rods 28.

Owing to the lightness of the seed cot ton it is difficult to give theair blast sufficient power to properly distribute the seed cotton acrossthe entire width of the cylin der. For this reason an apparatus whichwill now be described is employed as an auxiliary to the air blast.

At each end of the cylinder a horizontal beam 41 is extended betweenthe. uprights 20, said beam being located in each case slightly belowthe horizontal diameter of the cylinder. Adjacent to that side of thecylinder against which the air blast impinges, two parallel, horizontalshafts extemliiig from end to end of the cylinder are mounted inbearings 43, secured to the cross pieces 41. Each shaft 42 carries twoseries of arms 44 perpmulicular to each other and mounted closelyadjacent, said arms being extended equally from the shaft in eachdirection. The space between the two shafts 42 is such that the endportions of the rods carried by one shaft will extend between those ofthe other. as the two shafts are rotated. The shafts 42 each carry apulley 45 upon their rear extremities, which pulleys are adapted to bedriven by a belt 46 having its lower portion passed over a pulley 47carried by the rear end of one of the shafts 9. The belt 445 is crossedin order to communicate a like rotation to the shaft 4?, such that thearms 44 will supplement the blast of air in projecting the seed cottonacross the cylinder.

The construction of the cotton cleaning machine having been aboveexplained, a consecutive description of the operation will now be given.

A constant supply of seed cotton is fed into the chute 22. the rate offeeding being dependent upon speed of rotation of the cylinder and uponthe adjustment of the rock shaft 27. The fibers of the cotton will beengaged by the spikes projecting inwardly from the cylinder slats andthe cotton will therefore tend to adhere to the cylinder as the latterrotates in the direction indicated by the arrow in Fig. 1. As soon asthe cotton has been rotated to a point opposite the casing 39. he airblast issuing from said casing will in'unediately blow the cotton to'ard the center of the cylinder, the path along which it is blowntraversing the path traveled by the rapidly rotating arms 44. The speedof rotation of the two shafts 42 will be such that a considerablevelocity will be imparted to the seed cotton which is encountered by therods 44. so that. said cotton in falling will drop upon the inclinedrods farthest removed from said shaft 42. Some of the seed cotton willpass between the rotating rods 44, and the distance to which this isprojected will be less. Thus the cotton will be evenly distributed uponthe series of inclined rods 28, and in sliding from these rods to thebottom of the cylinder, the cotton will undergo a. slight for-- warddisplacement. After discharging from each series of inclined rods 28.the cotton will then again be subjected to a partial rotation upon thecylinder wall. and the forwardly deflected air blast will cause it tofall upon a series of rods somewhat nearer to the discharge outlet. Thusthe cotton will gradually feed from the inlet to the outlet extremity ofthe cylinder, during this process being thoroughly shaken up andfrequently discharged in a thoroughly distributed condition upon thecylinder bottom. It is obvious that during this process. all foreignmatter will have opportunity to sift out through the slats, falling tothe floor beneath the cylinder. This method of separating the foreignmatter from the seed cotton is dependent both upon the superior weightof the foreign matter and upon the fact that the foreign matter willhave no such tendency to adhere to the spikes as is inherent in thecotton owing to its fibrous nature. The amount of cotton therefore thatpasses between the slats of the cylinder will be negligible. Byadjusting the series of inclined rods 2% at different angles. the lengthof time required to pass the cotton through the cylinder may be subjccted to adjustment. this adjustment being largely dependent upon theamount of foreign matter contained in the cotton.

if some form of mechanically operated harvesting machine has beenemployed to gather the cotton. there is usually a large amount of hulls.leaves. twigs. etc, contained in the crop and the al)ove-descrilwdmachine will be found particularly ctficacious in removing such foreignmatter from machine picked cotton before such cotton is subjected to theordinary process of ginmng.

It will be seen that only a small number of the slots between members 5are subjected to the air blast at a time, thus permitting the spikes 7to carry the cotton up to the air blast so that it may be dislodged fromthe spikes and projected transversely of the. cylinder. The rods 28 arein the path of the projected cotton and it is caught thereby and thenagain delivered to the spikes.

It is obvious that various changes may be made in the form andproportions of parts and details of the above-described inventionwithout sacrificing the advantages or de ')arting from the spiritthereof, and the same is therefore presented as including all suchmtalitications as come within the scope of the following claims.
